Abstract :
Physicochemical features of freshwater bodies were regulated by number of factors. It includes temperature, turbidity, pH, total alkalinity, carbondioxide, dissolved oxygen, biological oxygen demand, chemical oxygen demand, phosphate, chloride and hardness. Present study focused on the determination of hydrobiological parameters during different seasons in January, 2011 – December, 2013 in three lakes of Miraj tahsil. The study indicated marked variation in some of the factors as turbidity, CO₂, DO, COD, Alkalinity etc. Obtained data showed, variations in pollution status of three lakes. As per observations and analysis contamination of lakes was Bharatnagar > Mhaishal > Brahmanath lake.
